I suck at explaining, so I'll see if i can find anything..
"Homosexuality has to do with what gender someone is attracted to. And just like people of all sexual orientations, people are going to have different preferences for the people they are attracted to. Just like some men/women prefer men/women that are skinny, and some prefer men/women that are overweight or have weight on them. Not everyone is going to understand their preference, but it's their preference. All in all, looks have NOTHING to do with what gender you are."
